Key message By combining data from different public and private breeding programs for genomic selection, we have increased the size and diversity of the training population, which has led to better predictions of grain yield and plant height in winter wheat compared to using individual training sets. Abstract The accuracy of genome-wide prediction is anticipated to improve with an increase in training population size. In our s...
Towards a Stable Host–Parasite Relationship Between Honey Bees and Varroa Mites Through Innovative BeekeepingNARA Subscribed
Varroa destructor is a major factor in declining honey bee health worldwide. Conventional beekeeping involves multiple Varroa treatments, limiting bees' ability to adapt to the mite. To foster a stable host–parasite relationship, we tested an “innovative” beekeeping method with fewer Varroa treatments, focusing on its impact on honey bee health. We compared Varroa mite fall, immune responses, and seasonal dynamics of Deformed...
Zusammenfassung Um die österreichischen Klimaziele zu erreichen, sind eine fundierte Datenbasis und belastbare Fakten erforderlich, damit politische und wirtschaftliche Entscheidungsträger*innen gezielte Maßnahmen zur notwendigen Umsetzung einleiten können. Das Projekt CaCTUS schließt bestehende Wissenslücken hinsichtlich des realistischen Potenzials von CO 2 -Abscheidung, -Nutzung und -Speicherung (CCUS) in Österreich und unt...
Thrombin receptor PAR4 cross-activates the tyrosine kinase c-met in atrial cardiomyocytesNARA Subscribed
Thrombin supports coagulation-independent inflammation via protease-activated receptors (PAR). PAR4 is specifically increased in obese human atria, correlating with NLRP3 inflammasome activation. PAR4-mediated NLRP3 inflammasome activation in atrial cardiomyocytes is not known, nor have signaling partners been identified. Thrombin transactivates the hepatocyte growth factor receptor in some cancer cells, so we examined PAR4/c-...
Direct and plant community mediated effects of management intensity on annual nutrient leaching risk in temperate grasslandsNARA Subscribed
Grassland management intensity influences nutrient cycling both directly, by changing nutrient inputs and outputs from the ecosystem, and indirectly, by altering the nutrient content, and the diversity and functional composition of plant and microbial communities. However, the relative importance of these direct and indirect processes for the leaching of multiple nutrients is poorly studied. We measured the annual leaching of...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Vision as oculomotor reward: cognitive contributions to the dynamic control of saccadic eye movementsNARA Subscribed
Humans and other primates are equipped with a foveated visual system. As a consequence, we reorient our fovea to objects and targets in the visual field that are conspicuous or that we consider relevant or worth looking at. These reorientations are achieved by means of saccadic eye movements. Where we saccade to depends on various low-level factors such as a targets’ luminance but also crucially on high-level factors like the...
Ecosystem transpiration and evaporation: Insights from three water flux partitioning methods across FLUXNET sitesNARA Subscribed
We apply and compare three widely applicable methods for estimating ecosystem transpiration ( T ) from eddy covariance (EC) data across 251 FLUXNET sites globally. All three methods are based on the coupled water and carbon relationship, but they differ in assumptions and parameterizations. Intercomparison of the three daily T estimates shows high correlation among methods ( R between .89 and .94), but a spread in magnitudes o...
The global abundance of tree palmsNARA Subscribed
Aim Palms are an iconic, diverse and often abundant component of tropical ecosystems that provide many ecosystem services. Being monocots, tree palms are evolutionarily, morphologically and physiologically distinct from other trees, and these differences have important consequences for ecosystem services (e.g., carbon sequestration and storage) and in terms of responses to climate change. We quantified global patterns of tree...
New insights into Southern Caucasian glacial–interglacial climate conditions inferred from Quaternary gastropod faunaNARA Subscribed
In the present study, we performed gastropod analyses on loess–palaeosol sequences from northeast Armenia (Southern Caucasia) covering at least three glacial–interglacial cycles. The elaborated ecostratigraphy shows significant patterns of species composition related to the succession of pedocomplexes and loess, respectively. Pedocomplexes included species that can be associated with high‐grass to forest‐steppe biomes, indicat...
Plant traits affecting herbivory on tree recruits in highly diverse subtropical forestsNARA Subscribed
Differences in herbivory among woody species can greatly affect the functioning of forest ecosystems, particularly in species‐rich (sub)tropical regions. However, the relative importance of the different plant traits which determine herbivore damage remains unclear. Defence traits can have strong effects on herbivory, but rarely studied geographical range characteristics could complement these effects through evolutionary asso...
